How to print prime number from 1 to n?

Answer 1

Hello @divyashree

def isPrime(n):

    # Corner case

    if n <= 1 :

        return False

    # check from 2 to n-1

    for i in range(2, n):

        if n % i == 0:

            return False

    return True

  

# Function to print primes

def printPrime(n):

    for i in range(2, n + 1):

        if isPrime(i):

            print(i, end = " ")

  

# Driver code

if __name__ == "__main__" :

    n = 7

    # function calling

    printPrime(n)

Hope it helps!!

Thank you!!
